OlL-SEPARATOFI.

SPECIFICATION forming part of Letters Patent No. 752,999, dated February23, 1904.

Application filed August 6, 1903- To all whom it may concern.-

Be it known that I, MiLLARD P. OSBOURN, of Merchantville, county ofCamden, and State of New Jersey, have invented an Improvement inOil-Separators, of which the following is a specification.

In separating oil from steam it has been found in many cases and withcertain grades of oil that a large portion of the oil is vaporized andcannot be removed by the ordinary arrangement of baflies orbafiie-plates. This difiiculty is due to the high temperature of thesteam and is aggravated when superheated steam is used. To overcome thisdifiiculty, I lower the temperature of the steam by suitablewater-cooled tubes immediately at its point of entrance to theseparator, so that the oil becomes more or less condensed from itsvaporous condition, owing to the lower temperature, and is more readilyprecipitated. To increase the precipitation of the oil from the steamafter the temperature has been lowered, I employ an expansion-chamberinto which the steam passes directly from the coolingtubes. Thisexpansion of the steam increases its volume and decreases its velocity,so that a large portion of the oil it contains will be precipitated tothe bottom of the separator beiore the steam passes to the usualbaflie-cham- In the drawings, Figure 1 is a longitudinal verticalsectional view of an oil-separator embodying my improvements. Fig. 2 isa transverse sectional view on the line A A of Fig. 1, and Fig. 3 is asimilar view on the line BB of Fig. 1.

The body of the separator consists of the usual outer shell a, havingheads a a formed, respectively, with the inlet 5 and outlet 0. Directlyadjacent to the inlet 6 is arranged a series of tubes 6, through whichcool water is circulated to cool the steam at the point of entrance. Inmy preferred construction these pipes are arranged vertically in one ormore rows and communicate at top and bottom with headers f f, formed inthe inlet-casting. The headers are shown formed with apertures closed byscrew-plugs g in line with the tubes seen No. 168,416. (No model.)

to facilitate cleaning and the removal and replacement of the tubes.Water is supplied by a supply-pipe h and is discharged through a pipe h.To save the heat given up by the steam through the cooling action of thetubes, the water which circulates through the tubes may be part of thefeed-water which reaches the boiler.

Back of the cooling-tubes e is an expansionchamber eof substantiallength through which the steam passes before reaching the bafflechamberand is permitted to expand. This expansion of the steam increases .itsvolume and decreases its velocity, and consequently the entrained oiland oily water will be more readily precipitated. Communicating directlywith the expansion chamber is the bafHechamber j, which may be of anysuitable construction. As shown, it is formed within the body abyhorizontal plates k is, between which are arranged a series of verticalbaflies m, preferably of the standard Webster form.

n is a dripchamber which communicates with the baffle-chamber through anopening 0 in the base of the shell (4. The lower plate is is perforated,so that the oil and oily water extracted by the baflies 772- may pass tothe outlet 0 and thence to the drip-chamber. The drip-chamber isprovided with a dischargeoutlet p, having a valve 1), which may beoperated or controlled in any suitable manner to discharge the contentsof the chamber a when they reach the proper level.

It will be noted that the cross-sectional area of the expansion-chamberz' is greater than that of the inlet and of the baflle chamber, so thatthe steam on passing between the cooling-tubes e is expanded in thechamber 6 before it passes to the baffle-chamber j.

By arranging the cooling-tubes e immediately adjacent to the inlet thesteam passes between them directly on entering the separator and beforereaching the expansion-chamher, so that the steam is cooled immediatelyon entering and is then expanded before it reaches the baflies m.

What I claim as new, and desire to secure by Letters Patent, is asfollows:

1. In anoil-separator, the combination of let, and water-tubes arrangedwithin the shell transversely in front of the inlet and forming a screenof water-cooled tubes through which the steam passes on entering theseparator and before reaching the baflies.

2. In an oil-separator, the combination of a shell having an inlet andan outlet, a Series of bafiies located between said inlet and out let,and water-tubes arranged within the shell transversely in front of theinlet and forming a screen of water-cooled tubes through which the steampasses directly on entering the separator and before reaching thebaflies, said shell being provided with an expansion-chamber betweensaid watertubes and baflies, whereby the steam is first cooled and thenexpanded before reaching the baflies.

8. An oil-separator consisting of an outer body having an inlet and anoutlet, and having a baflie-chamber provided with bafiies, the interiorof the separator between the inlet and baffle-chamber being of largercross-sectional area than the baffle-chamber and inlet to form anexpansion-chamber for the steam before it reaches the baffle-chamber.

4. In an oil-separator, the combination of an outer shell or body havingan inlet and an outlet, and a baffle-chamber adjacent to the outletformed by two parallel plates 79 70 within the outer shell and baffles mextending between said plates, said outer shell being formed with aninternal expansion-chamberibetween the inlet and baffle-chamber,

5. In an oil-separator, the combination of an outer shell or body havingan inlet and an outlet, a baffle-chamber adjacent to the outlet formedby two parallel plates 70 it within the outer shell and baffles mextending between said plates the lower plate It being perforated,

and a drip-chamber n communicating with the baffle-chamber through anopening 0 in the base of the shell below the lower perforatedbaflie-plate 70.

In testimony of which invention I hereunto set my hand.
